Whats the proper way to do Rspec with files or images on rails?

I'm doing an application that needs an upload of images that will later be displayed on another view but so far I haven't found the proper way to test it through a feature using Rspec with Capybara

this is the code a want to test

<%= f.label :photo, "Foto"%>
<%= f.file_field :photo%><br>

enter image description here

as an user seeing the page a I want to simulate the action of adding a photo or a file so it will be displayed like this

<dt>Foto</dt>
<dd><%= image_tag @applicant.photo %></dd>

When using Capybara you can upload files via file inputs using the attach_file method - https://rubydoc.info/github/teamcapybara/capybara/Capybara/Node/Actions#attach_file-instance_method The method takes a locator which is matched against the file input fields id, name, placeholder, associated labels text, etc. There are also a few other more specific options you can pass (see documentation). In your case that means any of

attach_file('applicant_photo', '/path/to/file/to/attach') # id
attach_file('applicant[photo]', '/path/to/file/to/attach') # name attribute
attach_file('Foto', '/path/to/file/to/attach') # associated label text

should work for you. Technically on a page that only has one visible file input field you could also just do

attach_file('/path/to/file/to/attach') # will use the only file input on page

attach_file also has a block accepting mode for use when the file input field is non-visible and the label is styled to give a more modern UI but that doesn't currently apply to your use case.
